speakers.

TELETEXT

The following are normal and are NOT malfunctions:
• When you touch the CRT surface, you might feel a slight charge of static electricity. This is because the CRT contains static
electricity; it does not affect the human body.
• The TV may emit a crackling sound due to a sudden change in temperature. There is no problem unless the picture or
sound is abnormal.
• When a bright a still image (of a white dress, for example) appears on the screen, the image may be coloured. This problem
occurs in all CRTs, and as the bright image disappears, such colouration also disappears.
• This TV is equipped with a microcomputer that may operate abnormally due to interference from external components. If
this happens, turn off the main power and disconnect the power cord from the AC socket. Then reconnect the power cord to
AC socket and turn on the main power again.
